12 Claims. I

This invention relates to a dust mop cleaner and has for one of its objects the provision of a device for cleaning a dust mop more efficiently than heretofore and without injury to the map.

Another object of the invention is a sanitary dust mop cleaner that is adapted to be foot operated and which cleaner is adapted to function as a holder for supporting the mop with the yarn or cords Oif the mop head suspended when the mop is not in use, and which cleaner is relatively small and easily and inconspicuously stored on the floor in a corner of a closet or room.

A still further object of the invention is a dust mop cleaner that is provided with a beater that is foot actuated for rapidly beating the mop head in the mos-t efficient manner for removing the dust therefrom, and which beater moves in a generally oscillatory manner.

Hereto-fore dust mop cleaners have been provided which, inv most instances have a rotary movement that tends to impart a rotary movement to the yarn or cords that go to make up the mop head. The mop'is not beaten. and the result is that much of the dust remains in the mop head.

Also, heretofore, the cleaners for dust mops have been relatively large, which is a serious objection, particularly where storage space is at a, premium and the housekeeper is critical as to appearances. A large, bulky device merely for cleaning the dust from a mop head is undesirable.

With the present invention, the cleaner is relatively small and is adapted to beat the mop head with sharp, strong blows from opposite sides and in a direction from the base or held ends of the cords generally toward their free outer ends whereby dust clinging to the cords will be certain to be knocked ofi. Also, with the present invention, the mop and cleaner are cooperatively formed for quick insertion of the mop head into the cleaner and within the same when the handle is swung to a vertical position and which mop may be quickly removed from the cleaner when desired by swinging the handle to a slightly inclined position and moving the mop laterally'.

Other objects and advantages will appear in the drawings and in the description.

In detail, the device shown in the drawings comprises a housing, generally designated I, having a pair of opposed end Walls 2, 3 (Fig. 2) opposed side walls 4, 5 (Figs. 3, 5) a bottom Wall 6 and a top wall 1.

The top wall I is formed with a central depression or channel 8. that extends longitudinally thereof from the edge adjacent end wall 3, and which channel terminates at about the center of the top wall. An upstanding rib 9 is formed in the bottom of channel 8 and longitudinally thereof, which rib, is centrally between the sides of said channel and becomes progressively higher in direction away from the end Wall 3. The inner end Of said rib terminates in a depression [0 (Figs. 10, 11') that extends transversely thereacross adjacent to the inner closed end of channel The upper portion of end wall 3 compr s s a door l2 (Fig. 3) that is hinged along its lower edge at l3 for swinging of its upper end downwardly. The hinge includes a horizontal hinge pin about which is a torsion spring l4 at a point intermediate its ends so connected with the door and end wall as yieldably to urge the door to a closed position at all times.

Provision for opening the door is by foot operated member l5 that projects outwardly from the wall 3. An upward extension Hi (Fig. 4) of said member extends through end wall 3 and upwardly, the upper end having a neck ll that projects into a recess [8 formed in the inner side of door I2. The end of said neck I! may be pivotally secured to said door in said recess as indicated, so that upon pressing downwardly on the projecting member l5 by the foot, the door will be swung downwardly and outwardly to the position seen in Fig. 4 whereby the head of a. mop, hereinafter described, may be inserted into said housing.

The mop best adapted for use with the present cleaner, may be of the type in which the yarn, string, or cords 19 are secured to a fabric sheet 20 and are adapted to depend from said sheet when the latter is horizontal. An upper sheet 2| is adapted to be secured along its edges to the edges of the sheet 20, except at one end where a gap between edges 22 is provided to enable the spring wire frame on the mop stick 23 to enter the space between sheets 20, 2|.

This frame comprises a wire 24 that is generally of U-shape to follow the contour of the edges of sheets 20, 2| and the ends of the legs of said U extend inwardly toward each other as at 25 (Fig. 9) for a short distance, and then outwardly of the sheets at the edges 22 of sheet 21 to return bends 26. From bends 26 the lengths 21 of wire extend over the upper sheet 2i and generally convergently to points about over the center of said sheet where their ends are connected by a straight length 28 that pivotally extends through a horizontal sleeve 29 eccentrically secured to the lower end of mop stick 23 in any suitable manner.

A strip 30 may connect the lengths 121 adjacent sleeve 25.

Sleeve 29 is centrally cut away along one side as at 32 (Fig. 9) and this cut away portion is adapted to slidably pass the upstanding rib 9 upon sliding the mop head into the housing through the opening in end wall 3 with the lengths ofwire 21 and the handle above top wall 1. However, when the mop head is fully within the housing, the sleeve is then over the transverse depression I and by swinging the handle 23 upwardly to vertical the side of sleeve 29 adjacent the cut away section 32 will rotate into the depression locking the mop head against removal from the housing until the handle is again swung downwardly a sufficient distance to enable the cut away portion to fit over the rib 9.

The fact that the sleeve 29 is eccentric to the handle enables the handle to stand vertically on its lower end when it is swung to vertical position, as best seen in Fig. 2. The handle may swing slightly past vertical to insure its weight holding it upright on the top wall I.

It is pertinent to note that the handle need not be swung to horizontal in order to remove the mop. Only a relatively slight inclination of say 20 degrees relative to vertical, or even less is sufi'icient. V

Within the upper end of the housing I is a mop head guide comprising a horizontally disposed U-shaped wire or rod 33. The free end 4 portions 34 (Fig. l) defining the sides of the U are inclined upwardly at about an angle of 45 and then extend oppositely outwardly to the sides of the housing to which the terminating ends are secured. The closed end of the U is secured to end wall 2 and the sides are spaced inwardly to generally follow the contour of the mop head. Upon insertion of the mop head into the housing, the flattened yarn or string will be engaged by the inclined ends of the guide, which will draw the same downwardly into the path of travel of the beater. The wire frame of the mop head will remain above the guide and adjacent the top of the housing. The closed end of the U is indicated at 35.

The foregoing explanation has been concerned with the step of getting the mop head into the housing. It may be quickly recovered by swinging the handle generally to the side in direction toward door l2 and then merely moving the mop out of the door. The door will automatically open under the force required to remove the mop head, although the operator may actuate the foot engaging member 15 if so desired.

The top wall 1 is preferably formed with small recesses 36 (Fig. 1) along the edge adjacent the door l2 to receive the return bends 26 of the wire 24. When the return bends are in said recesses 36, the door may be fully closed and is reasonably dusttight. The said door is provided with an inwardly projecting horizontally disposed rib 31 that is adjusted to force the depending strands on the mop into the path of the beater, as will later be explained.

In order to replace the fabric and strings of the mop head, it is merely necessary to force the return bends 26 toward each other until the wire frame 24 can be pulled out of its position between sheets 20, 2! through the gap in sheet '20 between the said edges 22.

Centrally positioned between the ends of the housing, and on the bottom, is a horizontally elongated box 49 extending at right angles to the horizontal longitudinal axis of the housing. This box 40 may comprise a fiat base strip 4i secured to the bottom 6 of the housing and over which is an inverted channel strip having sides 42, 43 and a bottom 44, the latter forming the top of the box. The sides of this channel strip are secured along their free lower edges to the fiat base strip 4|.

The said sides 42, 43 are cut away as at 44' (Figs. 5, 8), providing horizontally extending openings in said sides through which a cross bar 45 is adapted to extend with the opposite end portions of said bar projecting outwardly of opposite sides of said channel.

Adjacent and preferably in sliding contact with the opposite outer sides of said channel strip are seal plates 46 (Figs. 8, 9) through which the projecting ends of the cross bar 45 extend in a close fit. These plates have flanges 41 that extend toward each other over the upper sides of the top of box 49, and the length of said plates is sufiicient to cover said recesses 44 when the cross bar 45 is reciprocably moved in direction transversely thereof between opposite ends of said recesses.

A pair of rollers 48 are on bar 45 adjacent the inner sides of the side walls 42, 43 of the box 40. These roll on the base plate 4! when the bar is reciprocated.

A coil or helical spring 49 is within box 40 and is secured at one end to the bar 45 centrally between thev ends of the latter, while the other end oi said spring issecured to an end wall56 (Fig. that closes one end of thechannel strip forming the sides and top of said box 49. This spring tends at all times to hold the bar at the end of the recess 44' nearestend wall 59', and automatically returns bar 45 to said end of the recess when the bar is urged toward the. opposite end of said recess and released. 7

As seen in Fig. 5, the channel strip that forms thesides and top of box '40 extends through the side wall 4 of the housing I. Extending upwardly from the said-channel strip and adjacent the outer-side of side wall 4 is a channel strip generally designated 52. of said strip 52 are againstthe outer side of side wall 4, and coplanar flanges 54 projecting outwardly from said sides 53 along their free edges are secured to said side wall 4 by any suitable means.

The upper end or the channel strip 52 is provided with a bearing 55 that supports a roller 56 in a position atthe upper end of the said strip. This roller is between the adjacent sides of a pair of similar arcuately extending arms 58 constituting a link. A web 59 connects said arms ad jacent one of their ends, which web is curved longitudinally to follow the curves of the arms 58, and the roller 56 engages the convexly curved side of the web.

Said arms 58 extend through an opening formed in the side of wall 4 at their ends that are connected by said web, and upwardly alongside the side wall 4 above channel strips 52. The opposite ends of arms 58 extend into the box 49 through openings 60 formed in the upper side 44 of said box (Fig. 8). The terminating ends of the arms 58 within box 49 are secured to the cross bar 45.

From the description up to the present point it will be seen that by pushing downwardly on the ends of arms 58 that are outside the housing I, the cross bar 45 will be moved in the box 40 longitudinally of the latter and the spring 49 will be tensioned or expanded. The roller 56 will function to support the arms and to guide them through the openings into the housing, and the web 59 will not only function as a track in engagemeni; with roller 56, but it will tend to close the opening through which the arms and web extend into the housing.

Provision for pushing the upper ends of arms 58 downwardly is in the form of a foot pedal 6| that projects outwardly from the wall 4 of the housing. This pedal 6! has an upward extension 62. Extension 52 is in the form of a channel strip having a closed upper end 63 that extends over the upper end of arms 58, and sides 64. The arms 58 extend between sides 64 and are enclosed by said sides and by the wall 65 that connects the sides 64. A pivot 66 is carried by the upper end of the upward extension 62 to which the upper ends of arms 58 are pivoted. Also the pedal 6| and extension 62 may be swung outwardly on pivot 66 to expose the roller 56 and upper ends of arms 58 if desired. An anti-friction block 61 may be carried by the upward extension 62 of pedal 6i for slidable engagement with the outer surface of the bottom of channel strip 52. The said bottom of strip 52 may be longitudinally recessed to guide the block during sliding thereof.

By pressing downwardly on pedal 6] the cross bar 45 is moved in box 46 in direction away from side wall 4 and toward wall 5. Upon release of downward pressure on said pedal, the spring -49 will return the cross bar to its original position.

The free edges of sides 53- 6| and the outer ends 8 Arms 58 move longitudinally during fthe foregoing operation and substantially no gap exists in side-wa 4 where dust may escape from the box. I i

Pivotally. securedto the outwardly projecting ends'of cross bar 45 are one of the ends of a pair of beater arms 69. These arms 69 extend slantingly upwardly toward side wall 5 whenthe pedal of arms 58 are in their uppermost positions, and the upper ends of arms 69 remote from the cross bar 45 carry a horizontal beater rod or element l9 that extends through and between said upper ends and beater element 19 and the cross bar 45 is a cross rod ll that connects said arms, and a helical or coil spring 12 connects said cross rod with the top of box 46 at a point about midway between the end positions of the cross bar 45 when the latter is reci-procated.

- When the pedal 6i is moved downwardly and the cross bar 45 is moved toward wall 5, the beater arms 69 will also be moved toward the wall 5 carrying the beater element therewith, but as the spring 12 becomes tensioned, it will tend to pull the upper ends of arms 69 and the beater element toward wall 4 about the cross rod 45 as a pivot.

Adjacent wall 5 is a bracket member 13 that carries a pair of horizontally spaced bumpers 74. These bumpers are on a horizontal cross piece 15 that is secured to the upper end of the bracket, and the ends of the beater element that project outwardly of arms 69 rest on these bumpers when the pedal 6| is inoperative for causing actuation of the beater element. Said bumpers are preferably of resilient material, such as rubber, and function to take the shock of the element 10 at the one end of its stroke.

Adjacent the wall 4 is a cross piece 16 that is similar to cross piece 15 and that has bumpers l! thereon (Fig. 6)

These bumpers l4 and 11 are respectively on plates 18, 19 that are integral with the cross pieces 15, I6. Plates 18 have oppositely inwardly projecting lugs 86 thereon and plates 19 have similar oppositely inwardly projecting lugs 8| thereon.

The arms 69 have laterally oppositely outwardly directed flanges 82 along their upper edges, and similar flanges 83 along their lower edges (Figs. 5, 6) when the beater element is resting on bumpers 14.

Upon downward movement of the pedal 6| and consequent longitudinal movement of arms 69, the lower flanges 83 will pass below lugs on plates 78 and the arms cannot be swung to carry the beater element from a position adjacent wall 5 to a position in which the beater element rests on bumpers 11 until the flange passes from below the lugs 88. The result of this is that the outer upper ends of arms 69, and the beater element 70. moves upwardly to a point adjacent the upper ends of the depending mop strings before it is released, and during this upward movement the spring is tensioned so that appreciable power is stored before the arms are released.

The movement of the beater, when the arms are released, is generally downwardly and across the housing to the bumpers 11.

As soon as the foot pedal is released, after the beater has moved from its position adjacent wall 5 to bumpers 11, the spring 49 will not only elevate the pedal but will pull the cross rod back to the full line position shown in Fig. 5 with the equal distances outwardly thereof (Fig. 6). Between the result that flanges 82 will engage lugs 8| to cause the beater element to move upwardly before its release in the same manner as happened when the beater element was adjacent the opposite side of the housing and the pedal was depressed.

It is pertinent to note that the action of the beater element is quite fast when it is released and its movement is generally downwardly, the result being that the dust is thoroughly beaten from the mop. Only a few reciprccable movements of the beater element will clean the mob head. The mop may then be removed for use, or it may be left in the housing with the handle upright, in which position the mop head is concealed and the housing takes up but little more space than the mop head. Thus the cleaner becomes a support and storage device for the mop in addition to its cleaning function.

Inasmuch as the yarn or strings making up the body of the mop head become flattened out when the mop is used, the value of the guide 33 and the rib 31 on the door become apparent. Unless the flattened body of yarn, string or the like is positioned within the path of travel of the beater, the latter would not perform its function.

The guide 33 and rib 3'! insure the yarn or strings being pressed inwardly and below the guide 33, and the generally laterally and downward swing of the beater efiiciently beats the dust from the yarn or string and at the same time tends to straighten out the yarn or string for hanging vertically.

The closed end of the U, if anything, is wider than the width of the end of the mop adjacent thereto, thus facilitating the verticalstraightening of the yarn or string at the toe and of the mop head.

It is to be noted that the channel strip forming the sides and top of box 40 projects outwardly of the side of the housing to a point below the pedal 6. This projecting end of said strip engages the floor or any other supporting surface through a pad or foot 51 thereby stabilizing the cleaner during the cleaning operation, so it will not overturn as the pedal is vertically reciprocated.

In Fig. 12, the handle lock is most clearly shown for releasably locking the handle upright on the housing, although, as already stated it will tend to remain upright. The sleeve 29 has its opposite end edges outwardly recessed as indicated at 90 and the length 28 of the wire 21 may be split as at 29 between the ends of the sleeve so that the wire will spring into recesses 90 when the handle is vertical to hold said handle in a vertical position. When the handle is forcibly swung downwardly the wire will spring out of the recesses.
